This study presents photobiomodulation (PBM) therapy of the brain as an innovative treatment for various neurological and psychological conditions, including Parkinson’s disease, dementia, stroke, brain injury, and depression.
PBM uses light in the red to near‑infrared (NIR) range to stimulate complex IV of the mitochondrial respiratory chain and increase ATP synthesis, thereby promoting anti‑inflammatory and antioxidant responses, as well as neurogenesis.
PBM has been shown to enhance the metabolic capacity of neural cells and to provide various clinical benefits at the behavioral level, including improved cognitive function, antidepressant effects, and better sleep.
